Boston-based Liberty Mutual Insurance Co., which operates an industrial hygiene research facility in Hopkinton, has been assessed an $8,000 penalty by the Massachusetts Department of Environmental Protection (MassDEP) for violating state hazardous waste management and industrial wastewater regulations.
During a MassDEP inspection of the company’s 71 Frankland Road facility in June, MassDEP discovered that the company discharged industrial wastewater to an on-site sanitary septic system without first obtaining a groundwater discharge permit, according to a statement. Liberty Mutual also failed to comply with a number of hazardous waste management requirements, including a violation by the company that it accumulated hazardous waste longer than allowed under its permit.
